shellac! in the bay! @she_llac · 4h oh boy, just how much of internal ant infra is slop [quoted document excerpt] In addition, we found a fraction of runs had trained on a model's chain-of-thought by accident—something we work hard to avoid, out of concern that it teaches a model to hide its actual reasoning. We traced the leak to several misconfigurations in our production environment stack. [highlighted:] In doing so, it became clear that there were other issues born from messy code accumulating over time. [end highlight]
